Problems solved by technology

Among the five sample frames, the first and second sample frames use laser and photography methods, which improve the boundary determination and collection efficiency, but due to the size and It is heavy and inconvenient to carry and use in the field; the third type of telescopic rod is prone to telescopic failure during carrying and field use; the fourth type of splicing sample square is more complicated to operate when used in the field, and it is easy to cause the loss of splicing parts ; The fifth kind of tape measure quadrat is determined by the scale of the tape measure, the corners and boundaries of the quadrat are not easy to determine, and the area of ​​the quadrat is prone to errors

Abstract

The invention relates to a plant community investigation device, and particularly relates to a quadrat device for herbaceous plant community investigation. The device comprises a chargeable quadrat frame made of inelastic material; the quadrat frame is a rectangular structure without upper and lower bottom faces, and formed by four charging side walls under the state of fully filling with gas; theinner wall of every charging side wall is a rectangular face, and inner walls of adjacent two charging side walls are connected at a right angle. Compared with the existing quadrat frame, the quadratdevice can meet the demands of high accuracy, convenience of carrying, and low fault rate.

Description

technical field [0001] The invention relates to a plant community survey device, in particular to a quadrat device for herbaceous plant community survey. Background technique [0002] The investigation of species diversity and distribution patterns of herbaceous plant communities is an important part of ecological investigation. Considering the economy and feasibility of conducting a comprehensive survey of community species diversity and its distribution pattern in a region, the survey of community species diversity and its distribution pattern is generally carried out by sample method. After scientific research, the minimum surface area of ​​herbaceous plant communities is generally 1m 2 , so when investigating the species diversity and distribution patterns of herbaceous plant communities, typical survey plots are generally selected in the field research area, and multiple survey plots are arranged with a 1m×1m quadrat frame, and the statistics of the Based on informati...
